Ari Rabkin commented on CHUKWA-185:
-----------------------------------

What I was planning to do was this.  DTA takes a time cut-off, and will not 
stream files last modified before the cutoff.  So if you specify the epoch, you 
get everything.  Whenever DTA does a scan of the directory, it updates that 
cutoff to the time when the scan started.  So for a file that isn't being 
modified, DTA will start tailing it at most once.  

Time windowing for shutdown should be addressed by CHUKWA-204.

It might be reasonable to build a command line tool or script that stops all 
FTAs in a given subdirectory.  There's no need for that to be coupled to this 
patch in any way.  But I think we should have real use cases before we hack on 
it.

> Right now, FileTailingAdaptors watch particular files.   It'd be great to be 
> able to watch a whole path: to say something like /var/logs/*, where new logs 
> created in that directory get picked up.
